Introduction to Composite Construction

Strictly composite only means the interaction of two materials within one construction element (e.g.a concrete-filled tubular steel column) 0 the philosophy of mixed building technology includes the combination of construction elements or members built up with different construction methods (e.g.concrete column in combination with a composite beam and a prefabricated slab)
